Locked files (--lock): repo-authoritative entries. Checkpoint skips
them (preserves repo version). Status reports "drifted" instead of
"modified". Restore always overwrites if hash differs, no prompt.
Use case: system-managed files the OS overwrites.
Directory-only entries (--dir): track directory itself without
recursing. Restore ensures directory exists with correct permissions.
Use case: directories that must exist but contents are managed
elsewhere.
Add refactored to use AddOptions struct (Encrypt, Lock, DirOnly)
instead of variadic bools.
Proto: ManifestEntry gains locked field. convert.go updated.
7 new tests. ARCHITECTURE.md and README.md updated.
